WAGON-BODY LIFTER.

I v 2 Application filed April 2 4.,

To all whom it may concern: i

:Be it knownthatL-Lmrnnn O. MoCRAoKEN, a citizen of the United States, residing at Brush, in the county'of Morgan, State of Colorado, have invented certain new and useful Improvements in WagomBody L fters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable f others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in lifting devices and particularly to devices for lifting the bodies of hay racks from their running gears for the purpose of unloading the racks.

One object of the present invention is to provide a novel and improved device of this character whereby the wagon can be driven over the lifting device and the rack be automatically lifted therefrom.

Another object is to provide a novel and simple means for insuring the operatlon of the lifting means. 7

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of the invention in loweredposition, the wagon being arranged thereover.

Fig.- 2 is a side elevation of the device. showing it in raised position.

Fig. 3 is a rear elevation of the device 1n lowered position. I

Fig. 1 is a rear elevation of the device 1n elevated position,

Fig. 5 is a top plan view of the device.

Fig. 6 is a vertical transverse sectional view taken on the line 66 of Fig. 1. I

Referring particularly to the accompanying drawings, 10 represents a pair of vertical spaced posts which are secured in the ground at the point desired. At a sultable distance from these posts 10 there are secured in the ground similar posts 11, the posts 10 being connected to the posts 11 by the longitudinally extending beams 12.- Disposed above the beams 12 are the longitudinal beams 13. Pivotally connected to the. posts 10, at one end, and to the beams 13 at their other ends, are the lifting links 15. Similar links 16 are pivotally connected to the posts 11 and to the other ends of the .adapted to engage when the wagon is driven with its load, is driven beneath Specification ef Letters Patent 5 S t 1918.

beams 13'. that when the beams 13 into a horizontal position above the stationary beams 12, as clearly seen in Fig. 2 of the drawings. One end of each of thebeams-l2 extends a suitable distance. beyond the posts ll and has on its upper faces the ratchet teeth '17, thepurpose of which will presently appear. Secu'red'to thesides of. the beams-12,--adjacent the endsthereof, are the spaced strips 18, between which andthe said beams, the lifting links are arranged to. slide and beguided, where by the beams 13 will be, properly and, positively lifted vertically above the stationary beams 12. 'Pivota'lly connected to one end These links are-- of such length swung upwardly, they 1 will lift of each of the beams 13 is a pawl 19 which is adapted to engage with one of the sets of ratchefi. eeth of the beamsl2, when the movable beams are elevated, whereby'said movable beams will be held in elevated po-- sition with the wagon body or hay rack thereon, as seen in Fig. 2 oflthe drawings.

The hay rack is represented by the reference character 20, the front bolster of the wagon, by the character21, and the rear, bolster by the character 22. each sideof the rack is an arm 23, the purpose of which will appear in the description of the operation of the device. On the other ends of the, beams, 13 there are secured the vertically extending stop blocks. 24

Pivotally mounted on i against which the front'end of the rack is beneath the device; p

' In the operation of the device, the wagon,

the device until the rack engages with the blocks 24,

when the movable beams 13 will be swung forwardly and upwardly thereby. 3 When the rack has been raised-from the running 7 gear to a certain extent, the arms 23 are per-1 mitted to engage at their free ends with the forward side of the bolster, when further forward motion of the running gear will exert a forward and upward push on the mov- When the body of the rack is to be lowi together with T ered the pa'wls-19 are released from the.

ratchet teeth, but such a procedure would i I result in the'sudden falling of the movable beams and said wagon body. -To prevent this sudden falling of the body, I provide the following, retarding device whereby the body can be sloWly and'easily lowered onto the running gear of the Wagon. Between the posts 10 and 11 there is secured in the ground a short post 25 on whieh is pivotally mounted-a vertical lever 26 Which isconnected to the movable beams 13 by means of 20 same, strips connecting said stops and With messes them forming guides, links pivoted to the posts and leading upward through said guides, and movable beams carried by the upper ends of said links and adapted to be dropped. onto the fixed beams or raised above the same and held by contact of the links with said forward stops; combined With means I on the movable beams for engagement by the Wagon body to be lifted, a third link pivoted at one end to the midlength of each movable beam, and a control lever pivoted to the other end of this link, for the purpose set forth.
